in such cases, the word "physiological" refers to plant's (or any organism's) ability to get benefit from something to continue its life. i mean, it's about vital activities. so, except a few plants, most of them are intolerant to physiological drought. there is sufficient water but the plant can not use it. it can happen in various ways but in waterlogged soils, plant roots generally can't take enough air to maintain its vital activities because they are underwater completely. they need drainage also. shortly, the main parameter in using the word "physiological" is there is a living organism present.
the physical drought is only about the soil structure. in the simplest term, it occurs in soils which don't get enough waterfall and consequently don't have sufficient water. the most known example of an adaptation against drought is present in crassulaceae family. they have a thick cuticula and they are succulent plants. these prevent water loss and help them to continue their life cycle in soils which are physically dry. i hope this helps.

no, physiological drought is not a drought in fact. it's called physiological drought because plant can't use the water. it points the physiological disability of plant, not the structure of soil. this is why it's named "physiological" instead of "physical".
